Abstract

It was shown that the monophenylhydrazones of  1,5-diketones  are  converted by reduction with borohydride followed by treatment of the obtained hydrazino alcohols with acidic agents into derivatives of dihydropyran with the elimination of phenylhydrazine as the respective salt. γ,δ-Unsaturated ketones were isolated as side products of this reaction. The ways in which  these  compounds are formed are discussed.
